Chiral Dynamics Near Intra- and Inter-Band Exceptional Points under Dissipative Spin-Orbital-Angular-Momentum Coupling
Bo-Wen Liu, Ke-Ji Chen, Fan Wu +1
We study the parametric chiral dynamics of atoms under dissipative spin-orbital-angular-momentum coupling (SOAMC). With atoms confined in the ring-shaped potential of the Laguerre-…

Dynamic generation of superflow in a fermionic ring through phase imprinting
Ke-Ji Chen, Wei Yi, Fan Wu
We study the dynamic generation of persistent current by phase imprinting fermionic atoms in a ring geometry. Mediated by the pairing interaction, the Fermi condensate dynamically…

Emergence of Surface Superconductivity through Interference in Superconducting-proximity Topological Insulators
Yajiang Chen, Ke-Ji Chen, Jia-Ji Zhu +1
Superconducting-proximity topological insulators (STIs) have garnered significant research attention over the past two decades. In this Letter, we demonstrate that a low-dimensiona…
